Ever since Sax Rohmer conceived Dr. Fu Manchu, thriller writers have attempted to emulate his sinister appeal. No class of authors vied to out-villain Rohmer more than the pulp writers of the 1930s. The very best of these imitations was the work of top pulpateer Donald E. Keyhoe, later to make headlines as the retired Air Force officer who claimed that flying saucers were real.

Dr. Yen Sin lasted only three issues in 1936, but Keyhoe’s short-lived trilogy was a memorable attempt to give the “Yellow Peril” theme a mature and suspenseful treatment. The premise is a familiar one—a sinister Chinese super-scientist out to conquer the world. Pitted against him is the Q-Group, headed by State Department operative Michael Traile, who because of a childhood accident cannot sleep. Instead, he employs Yoga as a substitute. Under Traile are a host of secret agents, chief of whom is Eric Gordon of the F. B. I., who reports personally to Director John Glover—actually J. Edgar Hoover. Adding a dash of feminine mystique is Sin’s mysterious cohort, Sonya Damatri, while Eric Gordon’s girlfriend, Iris Vaughan, furnishes the series’ love interest.

Beginning with The Mystery of The Dragon’s Shadow and continuing through The Mystery of the Golden Skull and The Mystery of the Singing Mummies, the running battle between Dr. Yen Sin and his sleepless nemesis is a riveting roller-coaster ride of exotic torture, diabolic doom devices and sudden death that rages from Washington, D. C. to San Francisco! One wishes that Popular Publications had seen fit to publish the promised fourth installment, The Mystery of the Faceless Men…This series was that good!

Here is the suspenseful first encounter between Dr. Sin and the forces dedicated to destroying his Invisible Empire. The Mystery of the Dragon’s Shadow is read with appropriate gravity by Michael C. Gwynne. Also included are a trio of Chinatown tales by Frank Gruber, Arden X. Pangborn and radio’s famed Arch Obler.
